RS3 Laboratory D.C. Resistance Standards

The RS3 range of resistance standards are constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on the value, mounted on formers which have a high mechanical stability.

The wires are wound in a strain free manner and heat treated to remove any stresses. They are also artificially aged under the strictest control. The result is a standard of high quality with long term stability and permanence of calibration combined with a low temperature coefficient.

The RS3 range also offers a high current carrying capability which makes them ideal for applications where precise current needs to be measured.
